PURPOSE:To realize even stowage of coals by fixedly supporting a coal stowing upper conveyor on the upper part of a rotatably supported frame in the central part of a storage tank and supporting a lower conveyor movably in the direction of the upper conveyor on the lower part of said frame. CONSTITUTION:First, in case of stowing a coal M in the vicinity of the center of a cylindrical storage tank 1, the coal thrown into a thrown-in hopper 3 from a coal carrying in conveyor 4 is dropped on an upper conveyor 8 and then thrown into the storage tank 1 from the outside edge of said conveyor 8, which is rotated at this time in B direction by means of a driving device 15 and performs stowage covering the whole vicinity of the center. As for stowage in the vicinity of the inner wall of the storage tank 1 to be conducted by both conveyors 8, 9, the lower conveyor 9 is projected from a frame 5 up to a position (b) of a virtual line by means of a winch device 13. Through subsequent rotation of the frame 5 in B direction by means of the driving device 15, coals can be stowed covering the almost whole periphery in the vicinity of the inner wall. Accordingly, the efficiency of storage may be improved. |
